Answer: Barberry does well in full sun and has some thorns so I suppose it might help to keep children away. If however you meant something to protect children from the barberry, you might pair it with mugho pine or low growing junipers. These are evergreens that do great in similar growing situations -- full sun and well drained soil. Barberry grows maybe six inches to a foot a year at the most, it depends on the overall growing conditions and the weather each year. I hope this answers your question.
